Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591602, here are decompositions:

5 + 31591597 = 31591602
89 + 31591513 = 31591602
103 + 31591499 = 31591602
109 + 31591493 = 31591602
149 + 31591453 = 31591602
181 + 31591421 = 31591602
193 + 31591409 = 31591602
271 + 31591331 = 31591602

Showing the first eight; more decompositions exist.
